T havesho'wn a bed of this type in my copendin application filed on April 14, 1924, under erial #706,241, and issued as Patent No. 1,607,925, November 23, 1926, and the 35 present application forms adivision of said copending application in being drawn to the disclosure of Fig. l thereof.

Tn the drawings hereto Fig. l is a view corresponding to said Fig. i of the copending application and shows the bed folded to vertical position with dotted lines indicating its outfolded or horizontal position. Fig. 2

is a plan view of Fig. l, with the foot end of the bed broken away.

designated with the same numerals as used on the figures of the copending case so as to clearly identify therewith, but include some numerals taken from Fig. 1 of said case where lacking in original Fig. 4:. i

The construction shows a bed provided with a supporting frame comprising a head frame portion 28 and rigid therewith the lower frame portion 29 carrying the main pivots of the body portion 27 which is adapted to swing on pivots 30 from the vertical folded position 27 in full lines to the horizontal dotted position as extended for use.

A pair of casters 7 is provided for. the head frame portion of the bed, and spaced forward thereof is another pair of castors 26 arranged so as to provide a rolling sup-' port for the bed. The forward pair of casv l; A. foldmg'bed comprising a supporting tors 26 are supported each on a movable base portion 21 which is given a parallel horizontal movement by the arm 22 pivoted at its lower end to the base portion 21 and swinging about the pivot 23 carried by the body portion of the bed and which arm is it under the control of the lever 24 pivoted at The various parts of the drawings are April M, 192 Serial No. 706,241, new Patent R'o. 1,667,925.

its upper end the arm and at its lower end at 31 to the frame 29, and the link 25 pivoted at its upper end to said lever and at its lower end to the rear end of the movable base fthe front 'castors directly away from the rear casters and positions the front castors more towardthe foot 2 of the bed while firmly angular-ly braced to the bed portion 27 and the frame29. With the angular arrangement of levers" and links in the folded position shown in full lines the folded positionis stabilized as there is no tendency for the castors 26 to slip forward. This is duetoseveral factors including the narrow angles of the levers whenfolde-d-and to therearward pull on the bed portion 27 by reason of the springs and mattress normally carried by the bed and oc-. eupying the space between the body portion 27 and the head frame 28. The initial lowering movement of the bed 27- resulting more in a rearward thrust to rollers 7 rather thana forward thrust to rollers 26 and which ordinarily-is prevented from talking place acframe, a vertically arranged headpiece secured-to said supporting frame, abed portion pivoted near one end to said frame on a horizontal axis so as to swing from a vertical to a lowered horizontally extended position, floor castors on said fram a system of arms m pivoted to said bed portion and to said frame, a fioor castor carried by saidsystem of arms spaced forwardly from and cooperating, with said castors in supporting the frame withsaid head piece-vertical, and said system ofarms adapted and arranged to move said castor along the floor directly toward the foot of the bed upon lowering said bed por- Y tion.

2. A folding bed comprising a supporting frame, a vertically arranged head piece secured to said supporting frame, a bed portionpivotednear one end to said frame on a horizontal axis so as to-swing from a ver-- tical to a lowered horizontally extended po-. sitibn, a pair of floor castors on said frame, a system of arms at opposite sides of the bed 1 each pivoted to said bed portion and to said frame, a floor castor carried by each system of arms spaced forwardly from said castors and at all times cooperating therewith in supporting the frame, said system of arms adapted and arranged to each move its castor along the, floor longitudinally of the bed away from said castors upon lowering of the bed por- "tion, and also tomaintain the swivelling axis of the castor inoperative position.

3. A folding .bed comprising a supporting frame, a head piece secured to said frame, a bed portion pivoted near one end to said frame on a horizontal. axis so as to swing from a vertical to a lowered horizontal position, supporting castors on said frame, an additional castor at each side of the bed spaced for- NEIL SINCLAIR.

4. A foldable bed of the character described, comprising a supporting frame, a

bed frame pivoted Ladjacentone end to said supporting frame, a leg structure connected to said frames adjacent the pivotal point" thereof and for movement relative thereto, and separate anti-friction supporting members for the supporting-frame and forthe leg structure arranged to maintain an engagement with a floor to provide the sole support for the supporting frame-on the floor. and requiring mutual cooperation to hold said frame in stable equilibrium when the bed is in folded position.

5. A foldable bed of the character described, comprising a supporting'frame havmg a single pair of spaced supporting rollers fixed thereto, a bed frame pivoted adjacent one end to said supporting frame, a leg pivoted adjacent one end to said bed frame adjacent the pivotal point of said frames and i L 130i
